+* Freescale (Enhanced) Configurable Serial Peripheral Interface
+ (CSPI/eCSPI) for i.MX
+
+Required properties:
+- compatible : Should be "fsl,<soc>-cspi" or "fsl,<soc>-ecspi"
+- reg : Offset and length of the register set for the device
+- interrupts : Should contain CSPI/eCSPI interrupt
+- fsl,spi-num-chipselects : Contains the number of the chipselect
+- cs-gpios : Specifies the gpio pins to be used for chipselects.
+
+Example:
+
+ecspi@70010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx51-ecspi";
+ reg = <0x70010000 0x4000>;
+ interrupts = <36>;
+ fsl,spi-num-chipselects = <2>;
+ cs-gpios = <&gpio3 24 0>, /* GPIO4_24 */
+ <&gpio3 25 0>; /* GPIO4_25 */
+};
